Whole exome sequencing identifies FOXL2, FOXA2 and FOXA3 as candidate genes for monogenic congenital anomalies of the kidneys and urinary tract.

Nephrol Dial Transplant 2021 Sep 2. Epub 2021 Sep 2.

Department of Pediatrics, Boston Children's Hospital, Harvard Medical School, Boston, MA, USA.

Background: Congenital anomalies of the kidneys and urinary tract (CAKUT) constitute the most common cause of chronic kidney disease in the first three decades of life.

Potential benefits of functional magnetic resonance urography (fMRU) over MAG3 renal scan in children with obstructive uropathy.

J Pediatr Urol 2021 Jul 10. Epub 2021 Jul 10.

Division of Body Imaging, Department of Radiology, Children's Hospital of Philadelphia, Philadelphia, PA, USA; Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Introduction: Functional renal imaging, most commonly with MAG3 nuclear medicine renal scan, is recommended in the evaluation of children with urinary tract dilation (UTD) suspected of obstructive uropathy. Alternatively, renal function can be evaluated with functional Magnetic Resonance Urography (fMRU), which has superior anatomic detail. However, there are not enough data comparing both methods' equivalency. Read More

Minimal Invasive Treatment in Pelvic-Ureteric Junction Obstruction: A Comprehensive Review.

Res Rep Urol 2021 10;13:573-580. Epub 2021 Aug 10.

Department of Urology, Dr. Cipto Mangunkusumo Hospital, Jakarta, Indonesia.

Pelvic-ureteric junction obstruction (PUJO) is a common condition, and one of the lead causes of hydronephrosis in children. Currently, the gold standard treatment of PUJO is open surgery using the Anderson-Hynes-modified dismembered pyeloplasty technique. However, with the advancement of medical technology, several minimal invasive approaches were developed, including endoscopic, laparoscopic, and robotic approach, from which the best choice of surgical technique was yet to be determined.
